It worked for me! Had Poison Ivy, Now Have Hives!!!

It worked for me! Double dose of generic Zyrtek as soon as p.i. symptoms appeared forestalled the hives. I took the double dose for several days, then tapered to the regular dose for the rest of the week. No hives! Please consult your doctor before taking any medications. I do not have a medical degree or any authority to recommend treatment. I suggest that you take this information to your doctor and plan a personalized treatment together.
